IMPROVEMENT IN BROOM-VISES.

Specification forming part of Letters Patent No. 33,837, dated December 3, 1861.

To all whom it may concern:

Be it known that I, T. C. HARGRAvEs, of Schenectady, in the county of Schenectady and State of New York, have in vented an Improved Broom-Vise, the construction and operation of which I have described in the following specification and illustrated in its accompanying drawings with sufficient clearness to enable competent and skillful workmen in the arts to which it pertains or is most nearly allied to make and use my invention.

My said invention consists in the arrangement of parts in combination with each other, hereinafter described, by which the vise is made more serviceable for the purpose intended and cheaperof construction than those now in use.

This vise is intended for the purpose of holding brooms while the stitches are being put in to hold the corn below the handle.

In the accompanying drawings, Figure l is a plan of my improved broom-vise. Fig. 2 is a vertical longitudinal section showing the parts beyond the center, the handle or lever by which the pressure is applied being shown entire.

l is the bed-plate. It is made with an opening at 2 to allow the handle of the broom to pass through, and is provided with side ribs 3 3 to guide the sliding plate 4, which carries the movable jaw, and to support the crossplate 5, which supports the fixed jaw 6 of the vlse.

The plate l, side ribs 3 3, cross-plate 5, and lugs 9 constitute together a single casting. The sliding plate 4 also has side ribs or lugs 7, which support the cross-plate 8, the plate 4, side ribs 7, and cross-plate S also constituting a single casting. The plate S supports The plate 4 has also au opening at 10 to admit the handie of the broom. Toward its outer end or end farthest from the jaws the plate i is provided with a gear-rack 11 to allow the vise to be operated by means of the pinion 12 onthe `end of the lever 13. This lever is hung upon a pin 14, which is supported in the lugs 9.

To secure the plate 4 from sliding back when the lever 13 is released from the grasp of the hand after having been operated to clamp the broom, Iprovide a ratchet-rack l5 upon the plate ll, and secure over it in operating` position the pawl 16, hung upon a stud,

or pin 17 upon one of the lugs 9. The jaws 6 and 18 are so formed as to fit the proper form of a broom, being hollowed in the center with raised edges, which edges form a curve to iit around the edges of the broom. These raised portionsconverge toward the lower end or lower part of the jaw in such a manner as to conform to the taper of the broom, leaving at the bottom merely an opening for the passage of the handle. These jaws 6 and 1S are attached to the crossplates 5 and 8, respectively, by the screws 19 and 20, with steadylpins to prevent them from turning, or by any other desirable means. In addition to the raised edges of the jaws above described they are provided with iingers or side lugs 21, 22, 23, and 24, which not only insure the perfect gathering of the corn between the jaws of the vise, but also by matching with each other, as represented, keep the parts in place when pressure is applied, the finger 22 sliding under the inger 2]. and the nger 24 sliding over the finger 23, as shown. As these ngers are sufficiently long to allowthe vise to be open far enough to permit the insertion of the broom without allowing the corn to pass between their ends the object above mentioned of retaining the corn is perfectly secured.

A pair of auxiliary jaws 25 26 are attached above the jaws 6 and 18 to hold the broom,

during the operation of putting in the stitches nearest its brush end. They are secured in posit-ion during this time by the pins 27 27, which extend down into the cross-plates 5 and S, said pins fitting loosely, so that they may be easily removed. The jaws 25 26 are Asecured upon axes 2S 29 by means of arms 30 30, and when the row of stitches nearest the brush end of the broom has been put in the pins 27 27 are withdrawn and the jaws 25 26 folded back out of the way, so as to allow the next row of stitches to be put in.

By the arrangement above described the cross-plate 8, rack-gear ll, ratchet-rack 15, jaw 1S, fingers 22 2l, folding jaw 26, the pinion-lever 13, and the pawl 16, in combination with each other, substantially as set forth.
